Question

помогите пожалуйста!!!​

Answer 1

$( \frac{2x(x + 2)}{(x - 2)(x + 2)} - \frac{x - 2}{(x + 2)(x - 2)} ) \div \frac{6 {x}^{2} + 9x + 6 }{(x - 2)(x + 2)} = \frac{2 {x}^{2} + 4x - x + 2}{(x - 2)(x + 2)} \div \frac{6 {x}^{2} + 9x + 6 }{(x - 2)(x + 2)} = \frac{2 {x}^{2} + 3x + 2 \times (x - 2)(x + 2) }{(x - 2)(x + 2) \times 6 {x}^{2} + 9 x + 6} = \frac{1}{3 + 3 + 3} = \frac{1}{9}$
